FASTENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part f Letters Patent No. 370,560, dated September27', 1887.

Application filed February 21, 1887. Serial No. 228,333. (Model.)

To aZZ whom it may concern.-

Beit known that I, ADoLPH RIPPrEN, a citizen of the United States,residing in Reading, Berks county, Pennsylvania, have invented certainImprovements in Sash-Fasteners, of which the following is aspecification.

My invention consists of certain improvements in that class ofsash-fasteners in which a hooked latch-bolt on the lower sash is swungaround into engagement with a hooked keeper on the upper sash, and thetwo are then drawn together, so as to bring the sashes into contact,said sashes being thus not only locked together, but also prevented fromrattling.

My improvements comprise certain constructions and combinations ofparts, fully set forth and claimed hereinafter, the results of theimprovements being that the fastener presents a ener detached from eachother.

neat external appearance, is powerful in its action, yet easy ofoperation, andwhen in the locked position effectually prevents eitherthe spreading apart of the sashes or the forcing back of the latch-boltout of engagement with the keeper.

In the accompanying drawings, Figure l is a perspective view of myimproved fastener, parts of the upper and lower sashes being shown bydotted lines. Figs. 2, 3, and 4 are sectional pla-n views of thefastener, showing the parts in different positions. Fig. 5 is aperspective view showing the parts of the fast- Fig. 6 is an invertedperspective view of the latch-bolt,

and Fig. 7 is an inverted perspective view of tubular stud and having ahead, d, which iscontained in arecess, e, in the top of the hood,

the pin being secured to the base by riveting the lower end of the same,or by providing the same with a suitable nut or other retainer. On thebase are also three studs, f g 7i, the purpose of which will beexplained hereinafter.

The latch-bolt B has a projecting hook, 7c, at the outer end, shouldersIt k3 upon opposite sides, a recess, 7c', in one side, a centralelongated slot, z', and lugs j and m projecting from its upper face,while in the under side of said latch bolt is a radial groove, h', and asegmental groove, f,- the outer Wall of the lattewi1 having a notch, f2.

The cam-disk D has a projecting arm, D', by which the manipulation ofthe disk is eected, and said disk has a cam-slot, j', while on the underside of the disk is a beveled shoulder, m', terminating at the ends inrecesses ml and ma.

The hood F has in its side wall a recess for the reception of the armDlof the cam-disk, and a slot, F', for the projecting latch-bolt, thisslot being of sufficient dimensions to permit the necessary movement ofthe latch-bolt.

The hood, however, partakes of the rotating movement ofthe cam-disk.Hence this slot can be much less in dimensions than if the hood werestationary.

A spring, H, is interposed between the under side of the hood and thetop of the camdisk D, so as to press said cam-disk firmly upon thelatch-bolt and the latter upon the base-plate, and thus prevent anyloose fit of the parts, such as would cause them to rattle.

When the fastening is open, the parts ar-e in the position shown in Fig.2, and in order to close the fastening the cam-disk is turned in `thedirection of the arrow shown in said figure. cause the shoulder m on theunder side of the cam-disk to bear upon the lugv m of the latchbolt, andthereby cause the turning of said bolt with the disk, any longitudinalsliding movement of the bolt being prevented by contact of the segmentalinner end ofthe bolt with the stud g on the base-plate, and also byengagement of the stud j' on the base-plate with the segmental groovejin the under side The first effect of this movement is to of thelatch-bolt. The rotating movement of the latch-bolt with the cam-diskcontinues until the projecting stem of the bolt strikes the keeper G, asshown in Fig. 3, whereupon a longitudinal-sliding movement is impartedto the bolt by reason of the action of the camslot j upon the lug j,which projects from the upper1 side of the bolt. rlhislongitudinalsliding movement is permitted when the parts reach theposition shownin Fig. 3, for the stud g of the base-plate is now in linewith the recess k of the bolt, the stud It is in line with the groove7L', and the stud f is in line with the notch f2 at the end of thegroove f. When the parts reach the position shown in Fig. 4, thefastening ofthe sashes is completed, the longitudinal-sliding movementofthe bolt after its engagement with the keeper having had the effect ofdrawing the meetingrails of the sashes closely together.

Any attempt to pry the sashes apart without turning the cam-diskbackward is resisted, first, by the engagement of the lug j of the boltwith the cam-slotj of the disk, and, second, by reason of the fact thatthe lug m of the bolt occupies a position in the recess m2 in the underside of the cam-disk, which recess is diametrically in line with thepivotal center of the diskfso that separation of the sashes is resistedby the full strength of the tubular pivotstud and latch-bolt.

The turning of the latch-bolt backward, so as to free it from engagementwithv the keeper, is also effectually prevented by reason of theengagement of the stud 7L on the base-plate with the groove 71. in theunder side of the latch-bolt, and by the presence of the stud g in therecess 7c of the bolt.

A positive stop limits the movement of the latch-bolt in eitherdirection, and the movement of the cam-disk islikewise limited. Thus theforward-swinging movement of the latchbolt is limited by contact of theprojecting stem of the bolt with the lug f on the base,

irrespective of the stop provided by the keeper G, as reliance cannotalways be placed upon the latter being in proper line to serve of itselfas a stop for the bolt.

The inward-sliding movement of the-bolt is restricted by contact of theshoulder k2 with the stud g on the base, and the outward-slidingmovement is restricted by the contact of the stud f of the base with theinner wall of thesegmental groove f of thelatch-bolt, while thebackward-swinging movement of said bolt is restricted by contact of theshoulder 7c3 of the same with the stud h on the base. The forwardmovement of the cam-disk D is restricted by the lugs j and msof thebolt, which respectively enter the slot j and recess m2, the contact ofthe side wall of the hood F with the back of the latch-bolt stem alsoserving to restrict this movement, while backward movement of thecam-disk is arrested by the stud m entering the recess m3 in the underside of the disk, and by the contact of the side wall of the hood withthe front of the latch-bolt stem.

The hood F constitutes an important fea` ture of my improved fastener,as it covers, protects, and conceals the working parts of the fastener,and, as it is a separate piece, 1t is susceptible of being turned in alathe and polished or otherwise ornamented, so as to impart a neat andattractive appearance to the fastener.

Strength, stability, durability, and ease of operation also characterizemy improved fastener, owing to the precautions which I have taken forkeeping the latchbolt properly centered during its swinging movement, tothe fact that each movement is effected by a special cam, and becausepositive stops are employed to limit the movement of both the latch-boltand cam-disk and to prevent either the longitudinal or swinging movementof the bolt without the operation of said cam-disk.

I claim as my invention- 1. The combination, in a sash-fastener, of thebase-plate, the latch-bolt, and the camdisk, with a revolving hoodwhich' covers and protects the cam-disk and the hub of the bolt, saidhood being separate from the cam-disk and bolt and being slotted for thereception of the projecting stem of the bolt and the projecting arm ofthe cam-disk, all substantially as specified.

2. The combination of the base-plate having studs f and g, with thelatch-bolt having a segmental end for bearing against the stud g, asegmental groove for the reception of the stud f, and a notch throughwhich said stud can enter or leave the groove, all substantially asspecied.

3. The combination of the base-plate having a pivot-stud, the latch-bolthaving an'elongated slot for the reception kof said stud and having twoprojecting lugs upon its upper face, and the cam-disk having a shoulderfor acting upon one of said lugs to turn the bolt, and a cam-slot foracting upon the other lug to impart a longitudinal sliding movement tothe bolt, all substantially as specified.

4. The combination of the base-plate having a pivot-stud, the latch-bolthaving an elongated slot for the reception of said stud and havingprojecting lugs upon its upper face, and the cam-disk having a slotd foracting upon one lug to move the bolt longitudinally, and a shoulderwhich acts upon the other lug to turn the bolt and terminates in arecess for the reception of said lug when the turning movement iscompleted, all substantially as specified.

5. The combination of the base-plate having a pivot-stud, thelocking-bolt having an elongated slot for the reception of said stud andhaving projecting lugs upon its upper face, and the cam-disk having aslot for acting upon one lug to move the bolt longitudinally and ashoulder for acting upon the other lug to turn the bolt, said shoulderter- ICO IIO

minating at its opposite ends in recesses, one of which receives the lugwhen the disk has reached the limit of its movement in one direction,the other receiving the lug when the disk has reached the limit 01" itsmovement in the opposite direction, ail substantially as specified.

In testimony whereof I have signed my name to this specification inthepresence of two subscribing Witnesses.
